EGG-SEPARATING MECHANISI/I.

Application filed April 8, 1922, Serial No. 559,690. Renewed December20, 1923.

To (1 w/mm it may concern:

Be it known thatI, MINNIEK. JENKINS, a citizen of the, United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a certain new and useful Improvement in Egg Separatingliiechanisms, of whichthe following is a specification. a

My invention relates to improvements in egg separating mechanisms. Oneof the objects of my invention is to provide a novel egg separatingmeans by which the yolks and whites maybe sepa-. rated from each otherand fromveggs having broken yolks and with which the whites. and yolksof bad eggs may be prevented from contaminating good ones.

A further ob ect of my inventlon is to provide an eggseparatingmechanism of the kind described which is simple,cheap to make,sanitary, durable, not liable to get out of order, which is ellicient inoperation, and which has capacity for, largeproduction. i 1

further object of my ,invention is to" provide simple and novel meansforbreale;

ing the yolks of separated eggs. The novel features ofmy i hereinafterfully described and claimed;

In the accon'ran in drawin which illustrates the preferred embodiment myinvention,

Fig. is a plan view of my improved egg separating mechanism; 1 Fig. 2 isa side elevation of the same. Fig. 3 is a front elevation of the same.Fig. 4 is an enlarged perspective view of one of the spring clips.

Similar referencecharacters designate similar parts in the differentviews.

My improved mechanism provides two egg containers comprisingrespectively two troughs 1 and 2 which are pivotally mounted on asuitable support which may comprise a tray 3, to opposite ends ofwhichare se curedthe lower ends of two standards 4, the upper ends of whichare slotted and have fitted therein a horizontal plate 5, disposed edgeup, and which may be provided with a knifeedge 6, upon'whichv the shellsof the eggs'to be separated may bebroken.

- The trough 1 is disposed at one side of nvention are depositedin thetrough 1 the plate 5, and has its adjacent end closed and provided withtwo hooks 7, which are pivotally mounted in two holes 8, in the plate 5.I i The trough 2 hassecured to it a yoke 9 having a hook 10 which ispivotally mount ed in a hole 11, provided intheplate 5. The trough2 hasits end which is adjacent to the plate 5, closed, and its other endopen.

The troughs 1 and 2 are arranged to swing vertically from a holdingposition shown in solid lines in Fig. 2 to discharge positions shown indotted lines in said figure. The'troughs are arranged to swing bygravity} to said discharge position.

For lifting the trough'l from the discharge position to the holdingposition, I provide a wire U-shaped member 12, which is pivoted in. twoclips 13, which may be releasably attached to two sides of the tray Themember 12 intermediate of the clips 13 has an inverted U-shaped portion14: provided in its upper end, with an arcuate seat 15, 7

. adapted to receive the trongh 1. The mein ber 12 has at one end an arm16 by which the member may be swung. When the arm 16 is swungto theposition shown in solid lines in Figs. 1, 2and 3, the U-shaped portion14 will swing past the vertical and will raise-the trough 1 to and holdit in the holding position. The end of the member 12 opposite the arm 16is provided. with an arm 17 which will bear against the top of 55 thetray 3, for supportingthe U-shaped portion 14in the holding position. Byswinging the arm 16 to the dotted position shown in Figs. 1 and 2, thetray 1 will be per mitted to swing by gravity totheydischarge 99position, in which position whites of eggs will be discharged into areceptacle 18. p

Byraising the trough 1 at its open end,

it'isadaptedto discharge into the trough 2,if the open end be swungupwardly to a proper distance, and the trough tilted laterally, the sizeof the holes 8 permitting of such lateral tilting. r i. i 1

For supporting the trough 2 in the hold 1 ing position, shown in solidlines in Figs.

2 and 3, I provide a swinging member 19 which may consist of a piece ofwire pivoted in two clips 20, one 015 WhiOhiS show i Fig. 4:, and whichconsists preferably of sheet spring metal doubled on itself and adaptedto engage the side of the tray 3. Each clip 20 has at its upper end abarrel portion 21, in which is pivoted the wire member 19. Each member20 below the barrel portion 21 has a channel portion 22, adapted to fitthe wired upper end of the tray.

The member 19 has an inverted U-shaped portion 23, the transverseportion of which has two arcuate seats 24-, adapted to receive andsupport the trough 2 in the holding position shown in solid lines inFigs. 2 and 3. The trough 2 is adapted to be swung laterally on theplate 5, through the intermediacy of the yoke 9 and hook 10, to the twopositions shown in solid and dotted lines respectively in Fig. 1. \Vhenin either of these two positions, the trough 2 will be in one of theseats 24, when the swinging member 19 is in the holding position shownin Fig. 2, in which position the U-shaped portion 23 will inclineslightly inwardly and upwardly from the vertical, so that the weight ofthe trough 2 will retain the sup porting portion 23 in the holdingposition.

To swing the member 19 to and from the holding position, one end of saidmember is provided with an arm 25, which is adapted to be swung againstthe plate 5, to limit the inward swinging of said arm, after theportion23 has been swung slightly past the'ver tical. I

When the trough 2 is in the position shown in dotted lines in Fig. 1,said trough is adapted to discharge into a receptacle 26. When thetrough 2 is in the position shown in solid line in Fig. 1, it is adaptedto discharge into a receptacle 27. The latter may be employed to holdyolks. To break the yolks, as they pass out of the trough 2, suitablemeans may be provided, such as an upright pin 28, which has its lowerend fastened to the middle and bottom of the trough 2 adjacent to theouter end of thelatter. I

The receptacle 26 may be employed to hold eggs in which the yolks havebeen broken before being separated from the whites. The receptacles18,26 and 27 may be of any desired shape and capacity.

Any suitable means may be provided for separating the yolks and thewhites. In the drawings I have shown for this purpose, an

ordinary egg separating device comprising a bowl 29 having an arm 30attached to a frame 31 which rests upon the upper edge and embracesopposite sides of the plate 5, and which is adapted to be slid on theplate 5 from a position over the trough 1 to a position over the trough2 and then tilted to the position shown in dotted lines in Fig. 3,

- so as to have the cup 29 deposit a yolk carried therein into thetrough 2. For cutting the white from the yolk, there is provided a ringmember 32 adapted to fit over the upper end of the cup 29 and which hastwo arms 33 respectively pivoted to two ears 3 1 provided on the frame31.

In the operation of my invention, the egg shell is broken on the knifeedge 6 and the yolk with the white are deposited in the cup 29 when thelatter is in the position shown in solid lines in Fig. 1, over thetrough 1. The latter is disposed in the holding position shown in solidlines in Fig. 2, and also in Fig. 3.

The operator smells the egg, and if the latter is found to be bad, thetrough 1 and frame 31 are removed and cleansed and then replaced and theoperation just above described of depositing a white and a yolk in thecup 29' is repeated. If the yolk is broken and the egg is found to begood, the outer end of the trough 1 is tilted upwardly to permit theportion of the egg contained therein to pass into the trough 2, which atthe time is in the holding position, and the frame 1 is slid and tiltedso as to discharge the contents of the cup 29 into the trough 2, afterwhich the latter is swung laterally and lowered so as to discharge theyolk broken egg with its white into the receptacle 26.

If the egg which has been broken and the yolk discharged into the cup 29is a good egg and the yolk is unbroken, the ring member 32 is swung fromthe position shown in dotted lines in Fig; 2 to the position shown insolid lines in said figure, thus cutting the depending white of the eggfrom the yolk.- The white of the egg will be caught in the trough 1which is in the holding position, and the yolk is discharged from thecup 29 into the trough 2, which is also in the holding position, asalready described. The trough 2 is swung laterally and lowered so as todischarge the yolk into. the receptacle 27, the pin 28 breaking the.

yolk as it is discharged from the trough. The arm 16 is then swung tolower the trough 1 to the discharge position shown in dotted lines inFig. 2, upon which the white of the egg will be discharged intothereceptaole 18.

From the foregoing, it will be understood that in separating the eggs,the bad eggs may be caught and removed without con-' be easily andquickly and thoroughly cleansed, thus affording a sanitary apparatus.

plate 5 and fromthe troughs 1 and 2.

Thetroughs 1 and 2 may be quickly swung to the holding position byswinging the arms 16 and 25 from the positions shown in dotted lines'inFig. 2 to'the positions shown in solid lines in said figure.
